Simplifying 7 + 2(2v + -2) = 7 + 4v Reorder the terms: 7 + 2(-2 + 2v) = 7 + 4v 7 + (-2 * 2 + 2v * 2) = 7 + 4v 7 + (-4 + 4v) = 7 + 4v Combine like terms: 7 + -4 = 3 3 + 4v = 7 + 4v Add '-4v' to each side of the equation. 3 + 4v + -4v = 7 + 4v + -4v Combine like terms: 4v + -4v = 0 3 + 0 = 7 + 4v + -4v 3 = 7 + 4v + -4v Combine like terms: 4v + -4v = 0 3 = 7 + 0 3 = 7 Solving 3 = 7 Couldn't find a variable to solve for. This equation is invalid, the left and right sides are not equal, therefore there is no solution.
